TOKYO--(EON: Enhanced Online News)--Mitsui Chemicals, Inc. (Tokyo: 4183; President & CEO: Tsutomu Tannowa;

solution production facilities, which have been built at Nagoya Works to
accommodate growing domestic demand for lithium-ion battery-use
electrolyte solution.

2. Production capacity

5,000 tons/year

3. Startup

April 2017

Demand for lithium-ion batteries has expanded in line with growth of
laptop, smartphone, and tablet device markets. In the future,
eco-friendly hybrid and electric vehicles are expected to become
widespread in East Asia including China, and in Japan as well, growth in
the electrolyte solution market is forecasted especially for vehicles.

Mitsui Chemicals owns electrolyte solution production facilities at
Formosa Mitsui Advanced Chemicals Co., Ltd. (“FMAC”) in China, a joint
venture between Mitsui Chemicals and Formosa Plastics Corporation
(Taiwan: 1301; Chairman & President: Jason Lin; “Formosa Plastics”) to
respond to rising domestic demand for lithium-ion battery-use
electrolyte solution. Domestically, it has developed an electrolyte
solution business in the form of contract production. With the startup
of new facilities at Nagoya Works, Mitsui Chemicals intends to actively
promote domestic business expansion and gradually move away from its
existing contract production toward production at the new facilities.

Mitsui Chemicals is also advancing the expansion of its electrolyte
solution production facilities at FMAC for startup in November 2017, to
enhance the production and supply systems in preparation for further
market expansion.

Mitsui Chemicals has positioned the mobility domain as one of its key
growth drivers. Among other products, development of the lithium-ion
battery-use electrolyte solution is gathering momentum in this domain.
Mitsui Chemicals will put in place a system to produce and distribute
high quality electrolyte solution, taking advantage of its many years of
technical expertise. In doing so, it will continue to strengthen and
expand its electrolyte solution business with a focus on the mobility
domain.
